Least-Desirable Method for Preventing
Current Flow and Hydrogen Leakage
Turn off the capacitor module main switch,
then turn off the manual hydrogen shut-off
valve.
This method does not disable the airbags or the
seat belt tensioners.
It should be used only if the key switch is in the
ON (II) position, you cannot reach the key, and
you cannot reach under the hood.
Turning off the capacitor module main switch
prevents electric current from flowing into the
high-voltage cables from the capacitor module.
Turning off the manual hydrogen shut-off valve
stops the hydrogen flow from the fuel tanks.
Within 90 seconds, the fuel cells will stop
generating electricity, and electric current will
stop flowing into the high-voltage cables.
To use this method, do this:
1. Lift up the carpet covering the floor of the
cargo area.
2. Locate the capacitor module main switch at
the center of the cargo area floor.
